I don't get the "we fuck all the time" vibe from hearing "we are trying for a baby", but maybe because I've seen the reality of it; most people who are trying for a baby are informed enough to know that you don't need to go wild most of the month, and most people have been together for quite some time and have stressful day to day lives that don't allow (lust, time, and energy wise) for fucking all the time.
Usually "we are trying for a baby" implies they stopped using contraceptives and are tracking the cycle to fuck once or twice within the fertile window. It's not that different from regular sex within a long term relationship. (If trying for a baby makes you go wild and you fuck like bunnies every day for months on end more power to you though!)
But then again I am not disgusted by the idea of people having sex or bodily fluids. If they share TMI I'm usually just like "nice" or "good for you!" and enjoy the fact that they are open enough and we are close enough for me to hear details about their private life.
That being said, why would anyone at work share that they are trying for a baby to begin with? Work environment usually doesn't welcome pregnancy - it implies more sick leave, parental leave, and more emergency days off once the kid is older. Just saying "one day I'd like to start a family" makes you a less attractive person for a position. So I would always imply that I don't want kids, I don't want a family, I don't even like kids and I am infertile.
I understand doubting the white but seeing black in that gold was what I could never buy. To me it seemed like light blue-grey with matte gold.
